<DIV><SPAN style="FONT-SIZE: 12pt">Dear Jan Mathijs and co,</SPAN></DIV> <DIV><SPAN style="FONT-SIZE: 12pt">thank you for your previous reply. After several trials, i was able to run the script; the problem seems to have something to do with the space and resources allocated to the user on our server.</SPAN></DIV> <DIV><SPAN style="FONT-SIZE: 12pt"></SPAN> </DIV> <DIV><SPAN style="FONT-SIZE: 12pt">I am able to get probabilities of coherence (for my subject group) for each channel, time and frequency bins. I just wanted to check that I am reading the probabilities correctly: even thought the statistic test is non parametric, significant differences are denoted by probability values of <0.05? Is this right?</SPAN></DIV> <DIV><SPAN style="FONT-SIZE: 12pt"></SPAN> </DIV> <DIV><SPAN style="FONT-SIZE: 12pt">Many thanks again - it is very exciting to have group data coherence results, </SPAN></DIV>
